COMPOSITE WEAR PLATE FOR RAIL JOINTS.

Application filed February lG, 1927. Serial No. 168,704.

' This invention relates to rail joints, and

, in. the provision of a unit comprising a wear plate to be placed between the jointbar and the rails and filler abrasion plates adapted to provide more or less additional thickness to fit the fishing space of the rail. In that 13 connection it may be observed that one of the advantages of the invention is to. provide a construction which minimizes the effect of any irregularityin the roll surfaces of both the rails and the joint bars, while at the same time permitting thebars to be used on rails of ditferent'fishin spaces.

A further object of the invention is to provide a composite wear platefor rail joints which is separate from the joint bar that is, separately'handled or applierhbut cooperating therewith when the joint bars are assembled to constitute the joint.

With the above and other objects in view which will more readily appear as the nature of the invention is better understood, the same consistsin the novel construction, combination and arrangement of parts hereinafter more fullydescribed illustrated and claimed. i

In its primary aspect the present inven-' tion contemplates the combination of a rail joint bar designated generally as A and the composite wear plate or unit 13 which is adapted to be inserted in the fishing space of the rails R--R. The said unit-B 'comprises a wear plate 1 having anupper out- A preferred and practical embodiment of designate wardly extending bearing flange 2 and. a

lower outwardly extending flange 3 connected by an intermediate web portionw A. DISBROW, OFNEWROCHELLE, NEW YORK, AssIGNon TO THE RAIL JOINT COMPANY. or NEW YORK, N. Y.,

which ispreferably bowed for flexibility;

and the said flanges 2 and 3 cooperate with filler abrasion plates 4and5 respectively located at the head and foot of the bar to complete the unit. v

Therefore; the essential features and characteristics ofthe invention involve :the use of a wear plate including offset flanges adapted. to cooperate with filler abrasion. plates which may be interlocked. with the] flangesin any suitable and practical mau.

ner, as for example by welding. j

The filler abrasion plates 4 and 5 may be of any desired or required.length but are preferably relatively short strips of metal arranged at spaced intervals along the flanges of the wear plate to provide .full fishing height for the bar A at intervals and thus form well locatedbearing surfaces The above described fundamental features the abrasion plates 4 andfi arranged" between the head and foot of the bar stand the flanges 2 and 3 ofthe wear plate, while between the completed bar and the rail bean. ing surfaces. i 3 I so may be, embodied in various structural forms as will be apparent from the drawings. F or.

. example Figure 1 of the drawings illustrates.

the web of the wear plate'is slightly bowed outwardly to prov1de vertical adjustment andresiliencyto the plate thereby enabling itto accommodate and adjust itself to. 0on5 ditions'existing between the bar andfishing surfaces of the rail.

Figure 2, illustrates the same relative ar' rangement of filler abrasion.plateswith ref- 7 i erence to the flanges of the wear plate, and

the bowed web of the latter, follows the contour of the rail web.

Figures 3., 4 and 6 of the drawings illus trate the use ofthe filler abrasion plates between the flangesQ and 3 of the wear plate in the fishing surfaces at the head and foot of the rail. In Fig. 3 the web qu -follows the contour of the web of the joint bar while in Figure 4 the web 10* is bow-ed outwardly but out of contactwith the web of the joint bar, while F1g ure b illustrates the web w of the wear plate following the inside face of the bar and the upper and lower flanges thereof being offset as indicated at 2 and 3 to engage with an outer face of the bar.

In Figure 5 the-flanges 2 and 3 of the 'wear' plate are arranged between the upper'filler abrasion plates 4- and 4H and lower abrasion plates and fi respectively while thewcb portion 10'' is longitudinally coringated orcrimped. In this construction the wear plate is formed so to provide ii'orfia considerable variation in the. fishing height 01" the rails, and hence by varying the -'tl'iic-kness of the plates combined with it, it may be used as is the jointbar, for rails ofdifierent fishing;

From thewforegoing it will beapparen't that the present invention involves the use of a main or primary joint bar Awhich may be of standard cross sectional shape-or de sign'but preferably of smaller section and less vertical height than the fishing space oi the rail-with which it is intended to be used; butwhich constitutes in efiect abase or can" rier for the present-wear unitwhich consists of the hard metal wear plate and-acts as an abrasion'plate to take up wear between the joint =barand the rails; together-with" spaced strips or plates acting as lillersto provide the additional thickness requiredtofill the fishing spaces-0t :the railsi By r-eason of the fact that the bar- A is usually and preferably ofless fishing height than that-of 5 the rails the same may be readily mace" available for use in connection \vithrails-of ditlerent section thereby eii'ecting economy' in the cost o't'railsand the handling-0tthe same. Furthermore, in use, the con'lbined wear plate and joint bar provide a rail joint construction of increased'life and etfic iency' while at the same ti1ne,-contributing to the vertical flexibility of the joint, as well as facilitating the initial applicationor inst allation.

l/Vithout further description-it is' thought that the features andadvantagesof the invention will be readily apparent'to those" skilled in the art and it will out course be" understood that changes in theform,'-pr0- portion and minor-details of construction may be resorted to, without departing from the spirit'o't the invention and scope of the" appended claims.
